Luteinizing hormone/human chorionic gonadotropin receptors in myometrium and their role in uterine motility.
The object of this paper is the existence of LH/hCG receptors in female uterine tissue. Specific and high-affinity binding sites for LH are present in the pig and rabbit uterus. Estradiol promoted the synthesis of LH receptors in porcine myometrium. Stimulation of LH receptors with hCG in estrogen-primed tissue had a quiescence effect on myometrial contractility in vitro. The physiological role of uterine LH receptors in maintenance of myometrial quiescence is discussed.
